Not content to sequester himself to his own game and Soulcalibur V's stage of history, Ezio Auditore is making an appearance in Final Fantasy XIII-2 ... or at least his outfit is.
Ezio's Assassin's Creed Revelations get-up will be offered as a DLC outfit for Noel -- Noel Kreiss. "Release details for this downloadable content will be announced at a later date," the press release notes.
If you're concerned about Ezio's Italian finery looking too incongruous in the world of FFXIII-2 ... you haven't looked at the other characters in FFXIII-2 in a while. Congruity is a limited resource in Final Fantasy.
